Product Description
Allen-Bradley 1756-IB16ISOE/A
The Allen-Bradley 1756-IB16ISOE/A is a high-performance digital input module designed for the ControlLogix platform. It features 16 individually isolated 12/24V DC inputs, ensuring signal integrity and protection against ground loops. The standout feature of this module is its Sequencer of Events (SOE) capability, which allows it to capture and timestamp input state changes with high precision. This functionality is critical for applications requiring detailed event analysis, fault diagnostics, and understanding the exact sequence of operations in complex, high-speed industrial processes. The 1756-IB16ISOE/A installs into any available slot of a ControlLogix chassis and is configured using Studio 5000 Logix Designer software.
